An assembly of simultaneously transmitted electrically generated signals,
which contains a subset of binary spreading-code sequences that are
members of a larger set of binary spreading-code sequences available to a
particular node of a multi-node communication network. All sequences in
the set of spreading-code sequences available to the particular node of
the network can be generated by the same configuration of two
linear-feedback binary shift registers, where feedback taps of the two
linear-feedback binary shift registers correspond to primitive
polynomials of the same degree over GF(2), the field of two elements.
